i5 3570k 4.5Ghz @ 1.25v, Voltage isn't scaling down along with core speed

I OC'ed with a Gigabyte Z77x-D3H and Hyper 212 evo by

    Changing multiplier to 45
    Setting Vcore at 1.25
    Turbo power limit + core power limit to 45
    All the other settings I left at auto

When I'm idling or just web browsing the core speed reduces to about 1.6Ghz however the core voltage remains at 1.25.
Is it healthier for the CPU to scale the voltage down along with the core speed? If so how do I do so?

Idle- 15~20 Celsius
Load- 60 Celsius

To be honest that should not happen.

If your clock speed has gone down, it should draw lesser power on its own.
Go to bios and see if there is a Dynamic setting in VCORE tab.

That should fix it. Do you have Graphical User Interface in your bios? If yes then I guess I can help you out as I have Gigabyte board too and know the settings.

My bios looks like that (These are not my settings, just a random one i found on google)

check the watts that the CPU its pulling not the volt's,

Yeah those are similar to mine.

Go to MIT --> Advanced Frequency Settings --> Advanced CPU Core Features --> Turbo Power Limit and Core Current Limit --> On the blue button type 0 and hit enter. It should get back to auto (Dynamic).

Save and Restart.

What about LLC settings, or are they not present in your bios?

After a bit of trial and error I set the Vcore at normal which allowed me to adjust the offset voltage to +0.030v and changed LLC to medium. The Vcore is now reducing in proportion to the clock speed I.E. Idle 1.6Ghz -> VID 0.93v, V Core -> 0.94
